Calling openai.beta.chat.completions.runTools with gpt-4-32k returns error: "Additional properties are not allowed ('parsed', 'refusal' were unexpected)"

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

I am using the example from https://github.com/openai/openai-node/blob/master/examples/tool-call-helpers.ts and using OpenAI node SDK v.4.69.0.

When I execute the example using gpt-4-32k model, I receive the following error: BadRequestError: 400 Additional properties are not allowed ('parsed', 'refusal' were unexpected) - 'messages.2'

When I execute the example using gpt-4o model, the example works correctly.

I have been testing with different OpenAI node SDK versions. The last one where runTools actually works with this example is v.4.54.0. Once you upgrade to 4.55.x the error starts happening.

It could be related with the addition of Structured outputs that was added in 4.55.x.

I am using GPT models deployed in an Azure OpenAI service.

Maybe I should be doing something different to make it work with gpt-4-32k? (I haven't tested with gpt-4-1106-preview that is used in the example, but this should also work with gpt-4-32k, right?).

To Reproduce

• Use the example available at https://github.com/openai/openai-node/blob/master/examples/tool-call-helpers.ts
• Configure the OpenAI instance to use a GPT4 32k model.
• Execute the example

I can confirm that the error is still happening with version 4.73.0. I experienced the same issue with both GPT-4 and GPT-4 32k.

Thanks for the report and sorry for the delay, unfortunately I can't reproduce this issue.

@d-m1 can you share an example snippet? I tried just changing the examples/tool-call-helpers.ts script to use gpt-4-32k as mentioned in the original report but it works for me.

Hi @RobertCraigie, I used a gpt-4-32k model deployed with Azure OpenAI Services. Here is the code snippet that replicates the problem:

import { AzureOpenAI } from 'openai';
import { RunnableToolFunction } from 'openai/lib/RunnableFunction';

const endpoint = `https://${process.env.AZURE_OPENAI_API_INSTANCE_NAME!}.openai.azure.com/`
const apiKey = process.env.AZURE_OPENAI_API_KEY!;
const apiVersion = "2024-05-01-preview";
const deployment = process.env.AZURE_OPENAI_API_DEPLOYMENT_NAME; //This must match your deployment name.
const openai = new AzureOpenAI({ endpoint, apiKey, apiVersion, deployment });

async function list({ genre }: { genre: string }) {

main();

Running the above code using gpt-4-32k (or 1106-Preview) and using any OpenAI SDK version after 4.54.0 returns the following error (though it works with gpt-4o models):

...
new BadRequestError(status, error, message, headers);
BadRequestError: 400 Additional properties are not allowed ('parsed', 'refusal' were unexpected) - 'messages.2'
...

I am getting a similar error with 3.5 as well. Error when processing chat-post request: 400 Additional properties are not allowed ('parsed' was unexpected) - 'messages.2'. Using latest, 4.76.0
